Pre-Assignment Details

Significant events and approaches for the overall study
following participant enrollment, but prior to group assignment

A total of 149 patients were enrolled and 64 randomized to 1 of 8 treatment sequences (ABCDE, ABDCE, BACDE, BADCE, ABCD, ABDC, BACD, or BADC), with a 7-day washout period between treatments. Approximately 32 were to be discharged after Period 4, based on treatment sequence. Those remaining were to continue to and be discharged at end of Period 5.

Reporting Groups

Description

All Participants Who Received Treatment

All participants who received atazanavir with cobicistat in 1 of 8 treatment sequences (ABCDE, ABDCE, BACDE, BADCE, ABCD, ABDC, BACD, or BADC). Treatment A: Participants received a single dose of atazanavir, 300 mg as capsule, coadministered with cobicistat, 150 mg as tablet, following a light meal on Day 1 or 8. Treatment B: Participants received a single fixed-dose combination (FDC) of atazanavir, 300 mg/cobicistat, 150 mg, following a light meal on Day 1 or 8. Treatment C: Participants received a single dose of atazanavir, 300 mg as capsule, coadministered with cobicistat,150 mg as tablet, in the fasted state on Day15 or 22. Treatment D: Participants received a single FDC dose of atazanavir, 300 mg/cobicistat, 150 mg, in the fasted state on Day 15 or 22. Treatment E: Participants received a single FDC dose of atazanavir, 300 mg/cobicistat, 150 mg, following a high-fat meal on Day 29.

Principal Investigators are NOT employed by the organization sponsoring the study.

There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts
the PI's rights to discuss or publish trial results after the trial is completed.

The agreement is:

The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release
and can embargo communications regarding trial results for a period that is less than or equal to 60 days.
The sponsor cannot require changes to the communication and cannot extend the embargo.

The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release
and can embargo communications regarding trial results for a period that is more than 60 days but less than
or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.

Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.

Restriction Description:
Bristol-Myers Squibb Co. agreements with investigators vary; constant is our right to embargo communications regarding trial results prior to public release for a period ≤60 days from submittal for review. We will not prohibit investigators from publishing, but will prohibit the disclosure of previously undisclosed confidential information other than study results, and request postponement of single-center publications until after disclosure of the clinical trial's primary publication.
